First record of helminth parasites of Piabina thomasi (Characiformes: Characidae) from Salta, Argentina: population and community data

The aim of the present study was to analize the composition and the population and component community structure of helminth parasites of Piabina thomasi (Characiformes, Characidae) from Puerta de Díaz Reservoir, Northwestern Argentina. Eight taxa were found in 105 specimens collected between Novemb...

description The aim of the present study was to analize the composition and the population and component community structure of helminth parasites of Piabina thomasi (Characiformes, Characidae) from Puerta de Díaz Reservoir, Northwestern Argentina. Eight taxa were found in 105 specimens collected between November 2008 and April 2009: Gyrodactylus sp., Dactylogyridae gen. sp., Magnivitellinum simplex, Petasiger sp., Echinostomatidae gen. sp., Gryporhynchidae gen. sp., Procamallanus (Spirocamallanus) hilarii, and Contracaecum sp. Four taxa were autogenic, three were allogenic and one could be autogenic or allogenic species. Dactylogyridae gen. sp. (among adults) and Petasiger sp. (among larvae) were the taxa with higher prevalence and mean intensity. Significant variations were found between seasons in infrapopulations of Petasiger sp., Magnivitellinum simplex, Dactylogyridae gen. sp. and Gyrodactylus sp. Only the abundance of Dactylogyridae gen sp. and Echinostomatidae gen. sp. showed significant correlation with lenght of host. For the first time, Piabina thomasi is reported as a new host for Gyrodactylus sp., Dactylogyridae gen. sp., M. simplex, Petasiger sp., Echinostomatidae gen. sp., Gryporhynchidae gen. sp., P. (S.) hilarii, and Contracaecum sp. and Salta, as a new locality for the former six.
